Exploring the Top 5 Altcoins to Watch in 2021

1. Polkadot (DOT)

Polkadot is one of the most promising altcoins of 2021 due to its innovative, scalable, and secure network. With a market cap of over $35.5 billion, it's ranked ninth among the biggest cryptocurrencies by market cap. Introduced in 2020, Polkadot's popularity stems from its unique ability to connect several independent blockchain networks, enabling them to share their unique features. This feature makes it possible for Polkadot to embark on complex smart contract agreements, in addition to a variety of other applications.

2. Chainlink (LINK)

Chainlink is an Ethereum-based project that aims to provide secure, decentralized data links that connect blockchain technology with real-world applications. Chainlink already works with enormous companies like Oracle, Google, SWIFT, and more. Chainlink takes advantage of smart contracts to verify that the data transferred through its network is secure and accurate, making it a viable option for institutions looking for transparency and security in their data management.

3. Uniswap (UNI)

Launched in 2020, Uniswap is a decentralized exchange built on the Ethereum blockchain. Uniswap utilizes autonomous smart contracts, which allows users to exchange cryptocurrencies in a peer-to-peer and decentralized environment. If you're looking for complete control over your cryptocurrency assets, Uniswap is the right investment. Uniswap also offers governance token UNI that enables users to make crucial decisions concerning the platform's future development.

4. Polygon (MATIC)

Polygon, previously known as Matic Network, is an Ethereum-based protocol that provides faster, cheaper, and more straightforward methods for developers to create and execute decentralized applications. Polygon solves the Ethereum network's scalability and high-cost concerns, making it an attractive investment. Polygon's interoperability feature enables it to connect with complementary blockchains to provide broader decentralized finance (DeFi) service offerings.

5. Cardano (ADA)

Finally, we have Cardano on our list. Cardano is a blockchain platform that aims to offer quicker transaction processing speeds with additional smart contract features. Cardano uses its unique consensus algorithm (Ouroboros) to maintain the network's security and participate in governance decisions. The native token ADA, which is ranked 6th on the cryptocurrency market cap chart, is valuable because it is utilized to pay transaction fees and incentivize users to join the platform as validators. Cardano's development team has a reputation for releasing new upgrades, making it a viable investment for people that believe in continuous development within its network.
